Query Processing
IIapi_query()
Begins a query statement and allocates a statement handle, and can also allocate a transaction ID handle.
IIapi_batch()
Adds statements to a group of statements to be executed as a batch. Allocates a statement handle and can also allocate a transaction handle. For more information about IIapi_batch(), see
Batch Statement Execution.
Support for batch processing must be enabled in OpenAPI by initializing at API version 7 or greater. To initialize with this version, the application uses IIapi_initialize() and sets the in_version parameter to IIAPI_VERSION_7.
The DBMS must also support batch processing, which you can determine with the OpenAPI connection level. The connection level is returned by IIapi_connect() in the co_apiLevel parameter. A minimum level of IIAPI_LEVEL_6 is required.
